Based on the principle of the dynamic inverse problem,this paper discusses the method of structural dynamic design of a road paver's vibrating bar.At first,the paper analyzes the sensitivities of natural frequencies of the bar to its designing parameters and the key ones are found.Secondly,an artificial neural network is adopted to optimize the dynamics of the vibrating bar.A numerical example showing the effectiveness of the new method is provided.
